Adult tickets for a play cost $15 and child tickets cost $6. If there were 33 people at a performance and the theater collected $360 from ticket sales, how many children attended the play?
14 children
15 children
16 children
18 children

If you can't figure this out with an equation, try process of elimination.
14 @ 6 = 84
19 @ 15 = 285
285 + 84 = 369
Nope, the first one is not correct. 
If you need an equation.
let A = # adults
and C = # children
====================
number of attendees = 33; therefore,
A + C = 33
And cost of tickets was total of $360; therefore,
15*A + 6*C = 360
Solve the two equatins for A and C. 
thank you i just didn't know how to set it up
